摘　　要：Rapidio是处理嵌入式基础设施的新一代高速总线技术。其协议速率可达到10.3125Gbps^([1]),在如此高速率的接口速率下,交换电路中的路由表是各个端点之间进行信息高速交换的保证。针对这种用于高速交换电路使用的路由表,本文提出了一种高效的路由表设计。并对设计进行了代码设计与验证,验证表明本文提出的路由表能够满足目前接口速率下的性能要求。Rapidio is a new generation of high-speed bus technology for processing infrastructure of embedded system.Its protocol rate can reach up to 10.3125 Gbps, thus the routing table of the switching circuit is a guarantee of high-switching between end points in this high rate interface rate. This article propose a kind of high-efficiency routing table for this kind of high-speed switching circuit. Then use code design and verification to realize the design,the verification shows that the proposed routing table can satisfy the performance requirements under the current interface rate.
